SMOKE-PRODUCING DEVICE FOR ROU'IING WILD ANIMALS.

smoke and deliver it into the dens of wild animals, for the purpose of driving them therefrom, in order that they may be captured; and the invention has for its ob ect the production of a device of this kind in which a large volume of smoke may be acquired and be forcibly expelled from the device with a minimum loss of energy, or expelling force.

Figure I is a top or plan view of my smoke producing device. Fig. II is an enlarged longitudinal section of the smoke chamber and smoke conducting members, taken on the line III'I, Fig. I, with the bellows of the device shown in side elevation. Fig. III is a cross section taken on line III- III, Fig. I.

In the accompanying drawings: A designates a bellows, of any common form, that I is adapted to receive air, andfrom which the air is expelled through the nozzle ahaving a flanged flaring exit.

B designates a smoke chamber, that is preferably in the form of a cylinder and in I which may be placed a desirable quantity of may be derived within the smoke chamber v with a minimum amount of combustion.

The smoke production may be. accelerated and its effect amplified by the presence of sulfur, or other material, which will not only result in the production of smoke, but will also create obnoxious fumes.

The end of the smoke chamber B adjoining the bellows A is closed by a head 1, which constitutes a stopper for the chamber, and

The flap valve 5 is preferably made of asbestos, or other suitable nor' -combustible material; and, while it is of such flexibility as to enable it to be forced away from the end of the bellows nozzle under pressure of is closed by a head 7 which is provided with a central perforated exit member 8, through which smoke may be discharged from said chamber.

The nozzle 9 in turn receives an extension nozzle 10 that may be of any desirable length, suitable to convey smoke passing therethrough to considerable dis: tance into the hole or passageway leading to the den of an animal it may be desired to smoke out by the use of my smoke producing device.

In the use of my device, a quantity of slowly combustible and smoke producing ber B, whenthe head with its collar 2 is separated from the body of the vchamber B,

and such material is then ignited. The removable head of the smoke chamber is next attached to the body ofuthe chamber,- and The head 7 carries a tapering smoke conducting nozzle 9 that has a flaring 'material is introduced into the smoke chamthe bellows A is operated, whereby air is forcibly delivered into said chamber to cre ate a draft therein, that will result in slow combustion of the material in the smoke chamber, whereby a quantity of smoke is produced therein and forced therefrom through the perforated eXit member 8, into and through the delivery nozzles 9 and 10, from the latter of which it passes into the entranceway to the den of an animal it may be desired to rout by the use of my device.

The smoke chamber B is provided with a handle 11, by which the smoke producing device may be conveniently carried.

I claim The combination in a smoke producing device, of a bellows having a discharge nozzle formed with a peripheral flange providing a flat valve seat at its end, a combustion chamber head having a neck surrounding said discharge nozzle and closely fitted thereto, the said peripheral flange being arranged within said head and closely fitted to the inner face thereof so as to firmly secure said head to said nozzle, and a spring controlled valve secured to said head and seated on the peripheral flange at the end of said nozzle.
